Objective To explore the application effect of Baduanjin in elderly hypertensive patients with frailty. Methods A total of 67 elderly hypertensive outpatients with frailty were randomized into an intervention group (n=33) and a control group (n=34). The control group received routine treatment and health education, while the intervention group additionally received Baduanjin exercise intervention for 12 weeks. Before and after the intervention, the frailty score, SF-12 score, the gait speed, grip strength and blood pressure between the two groups were compared. Results After 12 weeks intervention, the frailty score, systolic blood pressure and diastolic blood pressure of the intervention group were significantly lower than those of the control group (P<0.05 for all), and the systolic and diastolic blood pressure of the two groups decreased with time going by; While the SF-12 score, grip strength and gait speed values were significantly higher than those of the control group (P<0.05 for all), and the grip strength and gait speed of the two groups increased with time going by. Conclusion Baduanjin exercise for elderly hypertensive patients with frailty can effectively improve their frailty status, reduce blood pressure and enhance their quality of life, and its effect is better than routine method.
